Traffic Management Plan Submissions

Duty of care

As stated in the Main Roads WA Traffic Management for Works on Roads - Code of Practice September 2018 (CoP); “Any party who undertakes work on a road that is open to traffic, by law has a “duty of care” under the Occupational Health and Safety Act to take all steps that are reasonably necessary to prevent any person being injured or damage being caused to the property of others while carrying out those works.
The Occupational Health and Safety Act specifically requires;

  • An employer to provide a safe workplace for its employees and
  • Any person in control of a workplace, to take measures to ensure persons who have access to that workplace (including road users in case of a roadworks site) are not exposed to hazards.

As part of this 'duty of care' any party undertaking works within a road reserve that is under the care, control and management of the City of Cockburn that presents a risk to, or impacts on road users is required to have approval to implement a Traffic Management Plan (TMP) from the City of Cockburn in accordance with the CoP.
